In A Western town a US Marshall corrals the townsfolk to take a stance and fight a gang boss who terrorizes them.

On the outskirts of the western town of Jericho, Alex Flood, an ex-lawman turned gang boss, ambushes a stagecoach carrying a single passenger--Dolan, once a U. S. marshal and now a professional gambler. After arriving in Jericho with the wounded stage driver, Ben Hickman, Dolan learns that the ruthless Flood is determined to wrest control of the stagecoach line from Ben and his attractive partner, Molly Lang. Molly refuses to yield to Flood's demands, however, and tries to rouse the townspeople into taking a stand against his lawlessness. Although Dolan is attracted to Molly, he considers her cause a hopeless one, and he leaves town, but he has a change of heart and returns to challenge Flood. Hastily formulating a plan of attack, Dolan and a handful of volunteers steal Flood's cattle, dynamite his ranch house and granary, and blow up his mine. As Flood makes plans to invade the town, Dolan and Molly rally enough supporters to wage a bloody gunfight. Flood shoots Ben in the back and then flees to a mountain wilderness, pursued by Dolan. When the two men confront each other in a clearing, Dolan kills Flood.
